赤谷系列春谷品种主要农艺与经济性状灰色关联分析

The Gray Relation Analysis in Major Agronomic and Economic Characters of Foxtail Millet of Chifeng Series Varieties

为提高谷子育种效率,找出赤峰地区谷子农艺与经济性状对于单株产量影响的重要性排序,应用灰色关联分析方法对赤谷系列谷子单株产量与农艺、经济性状之间的关系进行了研究。结果表明:穗重、草重、千粒重、生育期这四个性状与单株产量最为密切,节数、穗长、穗粗、株高对单株产量影响较小,在育种的性状选择中,应主要考虑穗重、草重、千粒重和生育期,兼顾其他性状。

In order to improve the efficiency of foxtail millet and to find the importance sorting of agronomic characters for the single plant yield of foxtail millet in Chifeng region,the gray correlation analysis method were used to analyze the relationship between the single plant yield and agronomic characters.The results showed that,four traits such as panicle weight,grass weight,mass of 1000 kernel,and fertility stage were most closely related to single plant yield while the number of articulation,ear length,ear diameter,plant height had less impact on single plant yield.The most important consideration in the selection of foxtail millet,characters such as panicle weight,grass weight,mass of 1000 kernel and developmental stage should be weighed more over other characters.
